There was a discussion a while back about drilling a hole in the tach case to
get to the pot in order to calibrate while assembled. I've also read about
problems with leaking capacitors. All of which is why I'm choosing to have
mine rebuilt.

(I think) all BJ8s have an electronic tach. Mine read high until I
calibrated it--it's
a simple process; just adjusting a trim pot(entiometer) on the back. I
think this
process is documented somewhere.
I'd try that before I'd "rebuild"--not sure there's much to rebuild in
there (esp. if
it's reading high).
